Over the past decade, technology and research have greatly expanded the functionality and aesthetics of prosthetic feet. Today, amputees have a wide array of feet from which to choose.

Prosthetic Socks and Liners

If I were to ask a room full of amputees what the most important feature of their prosthesis is, I am certain that comfort would be high on the list of responses. Without comfort, the most technologically sophisticated components become useless. At the most basic level, comfort within a prosthetic socket is achieved by good pressure distribution and the management of friction (shear) forces. Prosthetic socks and liners are the interface materials in contact with the residual limb and are integral to the comfort of the prosthesis.

Prosthetic Knee Systems

Of all prosthetic components, the knee system is arguably the most complex. It must provide reliable support when standing, allow smooth, controlled motion when walking, and permit unrestricted movement for sitting, bending and kneeling.

What You Might Expect During the First 12 Months as a Lower-Limb Amputee

As a recent amputee, you’re not alone if you feel clueless about what to expect during your first year as an amputee. While there are no set guidelines that will fit every amputee’s individual situation, there are some generalities that may apply. One certainty is that you will see your prosthetist many times during your first year as an amputee, possibly as many as 15 to 20 times, if not more. For this reason, you should do everything in your power to find a prosthetist that you are comfortable with.

Tips For Enhancing Your Success as a User of a Lower-Limb Prosthesis

Even for the most experienced wearers of lower-limb prostheses, using a prosthesis can result in daily inconveniences, if not worse. So what can recent amputees do to enhance their experience after being fitted with a prosthesis? First, accept that successful prosthesis use involves a 50/50 effort between the amputee and his or her prosthetist. Second, amputees need to understand that their prosthetist, in most cases, is not a miracle worker. In simplest terms, the prosthetist’s role is to assess the amputee’s physical potential, select appropriate prosthetic componentry, and provide a tool, in the form of a prosthesis, for the amputee to use to achieve his or her desired ADLs (activities of daily living). Once this is accomplished, it is up to the amputee to do the many things necessary to maximize the benefits offered by a comfortably fitting and properly functioning prosthesis.

Identifying and Managing Skin Issues With Lower-Limb Prosthetic Use

Fitting a prosthesis is complicated because parts of the human body are used for tasks for which they are not designed. The skin/prosthesis interface is at fault for many complications. Here, a synthetic material, such as silicone or plastic, is in constant contact with the skin. Skin is not well-suited for this type of material contact. Skin problems are one of the most common conditions affecting lower-limb prosthetic users today. Skin problems are experienced by approximately 75 percent of amputees using a lower-limb prosthesis. In fact, amputees experience nearly 65 percent more dermatological complaints than the general population.

The Importance of Gait Training

It is the goal of most every lower-limb amputee to walk “normally” again. In the context of this article, “normal” is defined as a symmetrical gait pattern that falls within the “average” range in terms of posture, step length, rate of speed, limb positioning, etc. But being a lower-limb amputee resents many different challenges when it comes to ambulating safely and without exerting excessive energy.

An Overview of Crutches

Everyone who has been confronted with a lower-extremity amputation has had to make decisions regarding mobility options. Many amputees opt for a prosthesis as their primary mode, wearing it (or them) full-time. Some prefer wearing their prosthesis part-time or for specific activities. In either scenario, the “must-have” equipment, the most important aid that a single-leg amputee could ever invest in, is a pair of appropriate crutches.

Focus on Bilateral Above-Knee Amputees

People who have experienced limb loss know that it only takes a moment for your life to be completely redefined. Yesterday, you were standing and walking. Today, you are in a hospital bed or a wheelchair. Tomorrow – well, tomorrow is uncertain and hard to even think about. Any amputation is life-altering, but people with bilateral above-knee amputations face a particularly complicated process of physical and emotional rehabilitation. The long-term goal is usually being able to walk again with prosthetic legs. However, even after months of rehabilitation, many people lose confidence that they will ever walk comfortably and independently. What can bilateral above-knee amputees do to increase the likelihood of getting their feet back on the ground? They can follow a graduated, four-step approach to becoming a prosthesis user.

The Prosthetic Knee

For the above-knee amputee, the prosthetic knee joint is one of the most critical components of the prosthesis. Replacing the amazingly complex human knee has been an ongoing challenge since the beginning of modern prosthetics. A prosthetic knee has to mimic the function of the normal knee while providing stability and safety at a reasonable weight and cost. A prosthetic knee that produces the most functional outcomes is needed. Developing such a knee requires familiarity with normal gait, because that is the basis for understanding an above-knee amputee’s gait.
